Title: Deep drawing tool for making automobile wheels - has sharp edge on central boss of punch and die to avoid need for hub-cap
Inventor: SCHURR HEINRICH
IPC: B21D53/26
Filed: 1977-05-13
Abstract: To suit present day trends in styling of cars, wheels of cast or forged light alloy are being more widely used and have no need for hub caps. With wheets of pressed steel there is usually a large radius on the edge of the central boss, due to the need to use relatively thick steel sheet or plate. A special deep drawing tool set consists of a punch and die so shaped that a sharp corner is formed around the edge of the central boss. The surface of the circumferential wall of the boss makes an acute angle with the flat surface of the boss. This renders a separate hub cap unnecessary.

Title: Crucible for extracting gas from solid samples - using graphite cup with holes around side to allow gas to escape
Inventor: GODAI TOMOKAZU
IPC: G01N30/06
Filed: 1977-09-30
Abstract: Extraction and analysis of gases contained in solid samples is carried out by use of a graphite crucible. This is gripped between cooled electrodes and subjected to an electric current. The heat so generated melts the sample in the crucible and releases the gas which is then carried off by a carrier gas entering from the top of the crucible. The gas leaves at approx. the same temp. as the crucible via openings around the edge of the wall. The crucible is first preheated to 2800 degrees C for >=50 sec. and a non-metallic sample injected. It is further maintained at >2000 degrees C for 60-180 sec. and the gas so produced is led off with the carrier gas flowing through. Used to determine the gas content of solid materials, esp. the content of H2, N2 and other elements. The basic system is well known but the hot gases rapidly touch water cooled Cu electrodes which cause various entrained compounds to solidify, thereby blocking the passageway out from the crucible. The system described ensures that the outlets are at the same temp. as the crucible and thus blockage does not occur.
